We can monitor progress of this chart, to have an idea of the extent of gold's strength, and wether we are better off holding either USD or Gold , as a hedge against our local currencies (like in my case, since I live in Argentina, I need to hedge against horrific ).
The advance here is capped, by the horizontal at the 129268.30 mark on chart, but there's a new quarterly time at mode signal on chart, which implies a 38.71% rally from current levels by or before Q3 2019.
To turn on gold vs foreign currencies, we'd need to see it drop under the blue box on chart, and stall here for one more quarter.
VIX, is implied volatility of options, an indicator we often use to help understand the activity in the S&P500.
It can be extremely useful but not directly related to gold, at least not in the light of this post's angle.
There's an observable phenomenon in silver and VIX, Tim West has a publication explaining it. I'll add the link here.
